Subject: [PATCH BUGFIX] clk: imx6q: fix typo in CAN clock definition
Date: Wed, 30 Mar 2016 14:23:03 +0200 [thread overview]
Message-ID: <1459340583-14743-1-git-send-email-LW@KARO-electronics.de> (raw)
commit ee36027427c7 ("clk: imx: Add clock support for imx6qp")
introduced a regression due to a subtle typo in the 'can_root' clock
definition. The effect is that trying to configure the bitrate of the
can interfaces fails with -EDOM or produces a division by zero error
due to the clock_freq of the can serial clock being reported as '0'.
